1. 27.89 mL of KNO3 solution in a 46.08 g container was evaporated and the dried, cooled container weighed 49.49 g. (a) What was the m/V% of the solution? (b) What was the concentration of the solution in molar?
2. Explain how to make 200.0 mL of a 3.14 M potassium iodide solution (KI).
3. How many mols of CaCl2 are in 15.0 mL of 0.430 M solution? If you add enough AgNO3 to the CaCl2 solution, what mass of AgCl would it make?
2AgNO3+ CaCl2→2AgCl(s)+ Ca(NO3
4. The molar mass of table sugar (sucrose) is 342.30 g/mol. You put in a pound of sugar (1.00#) to make a gallon of sugar solution (1.00 gal). (a) What is the concentration of the sugar in molar? (b) What mass of sugar would you get if you dried out 134.8 mL of this solution?
